Executive Summary — English → Spanish | 1 John 1–5

Why it matters

1 John is being added to a Spanish-language Bible curriculum that already has a mature, Romans-anchored Language Package. This letter shifts the terrain: fewer forensic/legal terms, far more relational and sensory vocabulary (light/darkness, abiding, seeing, testing spirits) — precisely the register where Hispanic Catholic sacramental/devotional practice and, in Caribbean and broader Latin American contexts, Espiritismo and Santería are most actively present in learners’ existing religious vocabulary. Getting this Language Package right determines whether learners hear 1 John’s own argument (direct confession to God, Christ’s sole advocacy, a present and certain new birth) or unconsciously assimilate it into competing frameworks (priest-mediated confession, saint/Marian advocacy, spiritist spirit-discernment, mortal/venial sin categories) that the letter itself does not teach.

Key findings

• 10 of 23 doctrines (43%) carry Critical risk, and 19 of 23 (83%) require mandatory human theologian review — a higher theologian-review proportion than the Romans baseline, driven by 1 John’s dense cluster of ontological claims (God is Light, God is Love), anti-docetic Christology, and direct-access soteriology.
• At the term level, 35 of 67 tracked terms (52%) are Critical or High risk (16 Critical, 19 High), spanning both terms inherited from the Romans baseline (righteousness, faith, sin, holy_spirit, son_of_god) and terms newly introduced by this letter (advocate, propitiation, come_in_the_flesh, born_of_god, savior, sin_unto_death, confess_sin, confess_christ, word_of_life, eternal_life).
• Two collision points exceed anything documented in the Romans baseline in acuteness: “abogado” (Advocate, 2:1) collides with the exact popular Hispanic Catholic title given to patron saints and the Virgin (“San Judas Tadeo, abogado de las causas difíciles”), and “probad los espíritus” (Test the Spirits, 4:1) collides with the live technical vocabulary of Espiritismo and Santería spirit-discernment through mediums.
• 1:9’s “confesamos” and 5:16’s “pecado de muerte” each risk being silently absorbed into entrenched Catholic sacramental/moral categories (confession requiring priestly absolution; the mortal/venial sin distinction) that this letter’s own argument does not support.
• Full-book coverage confirmed: all five chapters carry load-bearing doctrinal vocabulary; no chapter or section was silently omitted (see 11_doctrine_analysis.md).

Risks

• Critical-tier risk concentration is front-loaded and repeats at high frequency: unlike Romans’ more evenly distributed risk, 1 John’s Critical terms (light, love, born of God, advocate, propitiation, confession, incarnation/antichrist, eternal life, savior, sin unto death) recur dozens of times across only five chapters, so any single mistranslation compounds rapidly across the whole curriculum.
• Two structural, non-lexical risks require standing production rules rather than per-verse fixes: (1) the capitalization-only distinction between “Hijo de Dios” (Christ) and “hijos de Dios” (believers) is invisible in audio/oral delivery; (2) “mundo” (world) is genuinely dual-sense within the letter itself and cannot be resolved by word choice alone.
• Audience diversity compounds risk: the target audience spans cradle Catholic, nominally Christian, and Evangelical/Pentecostal backgrounds, each of which brings a different wrong default to the same term (e.g., “unción” collides with sacramental Anointing of the Sick for Catholic-formed readers and with charismatic-elite empowerment for Pentecostal-formed readers, simultaneously).

Opportunities

• 1 John’s own argument directly equips the fencing this package requires: the letter itself repeatedly makes the very distinctions (direct confession to God, 1:9; Christ’s sole advocacy, 2:1; a present and certain eternal life, 5:13) that correct the competing folk-religious and sacramental defaults — teaching notes can draw on the text’s own emphasis rather than importing outside polemic.
• Reuse of the Romans baseline’s proven method (exact-term enforcement, explicit fencing over lexical substitution, Critical/High/Medium/Low routing) extends cleanly to 1 John’s new vocabulary with no need to invent a new risk framework.
• The core passage (4:7–21) is doctrinally dense enough to serve as a single, well-fortified anchor for the majority of the letter’s highest-risk terms (God is Love, propitiation, Savior, confession of Christ, perfected love, assurance/confidence), concentrating theologian review effort efficiently.

Recommended actions

1. Load assets/translation_memory.json and assets/bible_term_registry.json (1 John versions) alongside the baseline Romans equivalents for every Phase 2 segment; never substitute alternatives for the 16 Critical and 19 High risk terms.
2. Route all 19 theologian-review doctrines and every segment containing a forbidden-substitution term (per analysis/12_ai_translation_requirements.md) through mandatory human theologian review before approval — no automated-only shortcut for these terms.
3. Apply the capitalization-integrity and “permanece”-consistency validation checks on every batch, given their compounding, whole-book-spanning risk profile.
4. Prioritize theologian review capacity on 1:5–2:2 and 4:1–21, the two sections carrying the highest concentration of Critical-tier doctrine in the letter.
5. Carry all findings forward unchanged into Phase 2 segment translation; this Language Package extends, and must never contradict, the baseline Romans package.
